STRUGGLE FOR EXISTENCE 119 



Increase in a geometrical ratio; that each at some period 

 of its life, during some season of the year, during each 

 generation or at intervals, has to struggle for life and to 

 suffer great destruction. When we reflect on this strug- 

 gle, we may console ourselves with the full belief that 

 the war of nature is not incessant, that no fear is felt, 

 that death is generally prompt, and that the vigorous, 

 the healthy, and the happy survive and multiply.
